From 56b4437f15ed2003413b857e08740576332e72d7 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Mon, 23 Nov 2015 21:22:30 +0530 Subject: ASoC: dapm: add a dapm sink widget DAPM models various widgets but lacks a sink widget. DSPs can have modules which take audio data, process it and are capable of generating events thus acting as a sink of data. To make the dapm graph complete for such paths we need a dapm sink widget for these modules, so add a SND_SOC_DAPM_SINK to declare such a widget. This widget will be treated as SND_SOC_DAPM_EP_SINK endpoint in the dapm graph Signed-off-by: Vinod Koul Reviewed-by: Lars-Peter Clausen Signed-off-by: Mark Brown --- sound/soc/soc-dapm.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'sound/soc/soc-dapm.c') diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index 016eba10b1ec..6760044f6aae 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -3351,6 +3351,11 @@ snd_soc_dapm_new_control_unlocked(struct snd_soc_dapm_context *dapm, w->is_ep = SND_SOC_DAPM_EP_SOURCE; w->power_check = dapm_always_on_check_power; break; + case snd_soc_dapm_sink: + w->is_ep = SND_SOC_DAPM_EP_SINK; + w->power_check = dapm_always_on_check_power; + break; + case snd_soc_dapm_mux: case snd_soc_dapm_demux: case snd_soc_dapm_switch: -- cgit v1.2.3
